There was a related link underneath that story with a great CBS piece on Joss, which I've never seen before and don't know if it was posted here. Has it? If not, here's the link. It has some great scenes from Much Ado, as well as an interview from before Avengers became the megamonstermoviethatatetheworld it is now.

Agree with KoC and Risch that 'Gun Machine' sounds intriguing. It stretches the phrase, "We've gotta get these two together," to the point where it ziiiiinnngs back and hit someone in the mouf, but Wastelanders sounds like a perfect combination of the guy who likes to write about guns and the guy who likes to write an accompanying lyric.
